On March 23, 1993, 19-year-old Carmen Van Huss was brutally murdered in her Indianapolis apartment while neighbors heard her screams but never called 911. For 31 years, the case went unsolved until Sergeant Bill Carter's relentless investigation and genetic genealogy finally identified Dana Shepard as her killer, leading to his guilty plea and Carmen's Law—groundbreaking legislation expanding DNA testing access for cold cases. Genetic genealogy and crowdfunded DNA testing solved a 31-year-old murder that traditional investigation could not, after police bureaucracy initially blocked testing efforts.
